technical field

The present invention relates to a pixel structure, a touch display panel and a liquid crystal display, and in particular to a fringe field switching pixel structure, a touch display panel and a liquid crystal display.

Background technique

In recent years, with the maturity of optoelectronic technology and semiconductor manufacturing technology, the flat panel display (FlatPanelDisplay) has been vigorously developed. Liquid crystal displays have gradually replaced traditional cathode ray tube displays due to their advantages of low-voltage operation, no radiation scattering, light weight, and small size, and have become the mainstream of display products in recent years. However, liquid crystal displays still have the problem of limited viewing angles. At present, the technologies that can meet the requirements of wide viewing angle include twisted nematic (twistednematic, TN) liquid crystal plus wide viewing film (wideviewing film), in-plane switching (IPS) liquid crystal display, fringe field switching (FringeFieldSwitching , FFS) liquid crystal display and multi-domain vertical alignment (Multi-domainverticallyalignment, MVA) liquid crystal display. Here, the known fringe field switching liquid crystal display is described.

In the known fringe field switching liquid crystal display, the schematic top view and schematic cross-sectional design of the pixel structure are shown in FIG. 1A and FIG. 1B . Please refer to FIG. 1A and FIG. 1B at the same time. The pixel structure 100 is disposed on a substrate 10. The pixel structure 100 includes at least one scanning line 102, at least one data line 104, an active element 106, a first electrode 108 and a second electrode. 110. The scan line 102 and the data line 104 enclose a rectangular pixel area P, and the first electrode 108 and the second electrode 110 are located in the rectangular pixel area P, and the second electrode 110 is electrically connected to the active device 106 . In addition, the second electrode 110 is disposed between the first electrode 108 and the substrate 10, and the first electrode 108 has a plurality of slits 108A to expose part of the second electrode 110, that is, the conductive pattern of the first electrode 108 is in a plurality of A portion of the slit 108A does not overlap the second electrode 110 .

It is worth mentioning that the first electrode 108 is not electrically connected to the active device 106 , but is electrically connected to another common voltage source (not shown). When the pixel structure 100 is displaying, the first electrode 108 and the second electrode 110 will be input with different voltages to generate a fringe electric field effect so that the liquid crystal display can display a display effect with a wide viewing angle.

Although the pixel structure 100 is helpful to improve the display effect of the liquid crystal display, when the liquid crystal display with the pixel structure 100 is laminated with a touch panel to form a touch display panel, some undesirable phenomena may occur. For example, when the user presses the above-mentioned touch-sensitive display panel, the liquid crystal molecules in the liquid crystal display may be disturbed and present an undesirable alignment state. Therefore, there will be uneven brightness around the touch point, which will affect the recognition of touch or handwriting input. At this time, the slit 108A of the pixel structure 100 may affect the time for the disturbed liquid crystal molecules to return to their original state. In particular, the longer the length of the slit 108A, the longer the recovery time of the liquid crystal molecules is likely to be extended.

detailed description

In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments will be described in detail below together with the accompanying drawings.

It can be seen from the background art that the pixel structure 100 in FIG. 1A can provide a marginal electric field effect to achieve a wide viewing angle display effect. However, the design of the pixel structure 100 has a long and narrow slit 110A. When the pixel structure 100 is applied to a touch display panel, there is a problem that the recovery time of liquid crystal molecules is limited by the length of the slit 110A. Therefore, in order to make liquid crystal molecules have better recovery efficiency without changing the design of the original pixel structure 100 , the present invention proposes the following fringe field switching pixel structures.

2A and 2B are respectively a schematic top view and a schematic cross-sectional view of a pixel structure according to a first embodiment of the present invention. Please refer to FIG. 2A and FIG. 2B simultaneously, the pixel structure 200 is disposed on a substrate 20 . The pixel structure 200 includes at least one scan line 210 , at least one data line 220 , an active device 230 , a first electrode 240 and a second electrode 250 . The scan line 210 intersects the data line 220 to define a rectangular pixel region P. As shown in FIG. The active device 230 is electrically connected to the scan line 210 and the data line 220 . The first electrode 240 has a plurality of stripe patterns 242 and a plurality of connection patterns 244 located in the rectangular pixel region P. As shown in FIG. Each connection pattern 244 connects the middle or adjacent middle parts of two adjacent stripe patterns 242 to define two slits 246 between the two adjacent stripe patterns 242 . In this embodiment, the number of slits 246 is twice the number of connection patterns 244 . The second electrode 250 is located between the first electrode 240 and the substrate 20, and the slit 246 exposes part of the second electrode 250, that is, the first electrode 240 does not overlap with the second electrode 250 at the part of the plurality of slits 246, But the part of the stripe pattern 242 and the connection pattern 244 will overlap with the second electrode 250 .

Specifically, the rectangular pixel area P may have a long side and a wide side, wherein the length L of the long side is greater than the length W of the wide side. The angle between the extending direction of the slit 246 and the long side of the rectangular pixel area P is θ, that is, the angle between the extending direction of the slit 246 and the long side is θ. In this embodiment, the extending direction of the slits 246 may be parallel to the long side of the rectangular pixel area P, that is, the included angle is θ=0°, so in this embodiment, the included angle θ is not specially marked. . However, in other embodiments, the included angle can also be between 0° and 45°, that is, 0°≦θ<45°, such as the embodiment shown in FIG. 4A to FIG. 4D , which will be described in detail later. In addition, the stripe pattern 242 in this embodiment is a plurality of straight line patterns, and the connection pattern 244 is arranged along a straight line as an example. That is to say, in the pixel structure 200 of this embodiment, the first electrode 240 presents a fence-like pattern design. In practice, each slit 246 is independent, and each slit 246 is an elongated slit whose extension direction is close to or parallel to the extension direction of the long side.

In addition, in the pixel structure 200 , the second electrode 250 is completely disposed in the rectangular pixel region P on the substrate 20 , that is, the second electrode 250 does not have patterns such as slits. Meanwhile, the active device 230 is electrically connected to the second electrode 250 and electrically insulated from the first electrode 240 . In other words, the second electrode 250 is a pixel electrode in the pixel structure 200 . When the pixel structure 200 is displaying, the second electrode 250 receives the data signal transmitted by the data line 220 , and the first electrode 240 is input with a common signal provided by the common voltage source (not shown). At this moment, the first electrode 240 with a fence-like design exposes part of the second electrode 250 , and a marginal electric field effect is generated at the location of the slit 246 . Therefore, the application of the pixel structure 200 in a liquid crystal display can achieve the effect of a wide viewing angle display effect.

However, the first electrode 240 of this embodiment is not limited to the above design. For example, FIG. 2C to FIG. 2F are various first pixel electrode designs of the pixel structure of the first embodiment of the present invention. The connection patterns 244 mentioned above can also be arranged alternately instead of in a straight line, and the number of the slits 246 is twice the number of the connection patterns 244 , as shown in FIG. 2C . Of course, it can be seen from FIG. 2D to FIG. 2F that the connection pattern 244 can connect any two adjacent stripe patterns 242 , and can also selectively connect only part of the adjacent stripe patterns 242 . Therefore, although the number of the slits 246 is twice the number of the connection patterns 244 , there are slits 248 not defined by the connection patterns 244 , so the number of the overall slits is greater than the number of the connection patterns 244 . Likewise, these connection patterns 244 can be arranged in a straight line or in a staggered arrangement.

Furthermore, in this embodiment, both ends of each stripe pattern 242 face to two opposite wide sides of the rectangular pixel region P, respectively. Therefore, the connection pattern 244 of the present embodiment is designed such that the first electrode 240 in each rectangular pixel region P has at least two slits 246 along the extending direction of the long side. That is to say, compared with the known pixel structure 100 , in the pixel structure 200 of the present embodiment, the length of at least part of the slits 246 is shorter than the known design. Specifically, the relationship between the length L of the long side of the rectangular pixel region P and the length Γ of the slit 346 in this embodiment may be 0.50L<Γ<0.71L.

In the first embodiment, the active device 230 is electrically connected to the second electrode 250 , but the active device 230 may actually be electrically connected to the first electrode 240 . 3A and 3B are respectively a schematic top view and a schematic cross-sectional view of a pixel structure according to a second embodiment of the present invention. Please refer to FIG. 3A and FIG. 3B at the same time, the pixel structure 300 is substantially the same as the pixel structure 200 , and the active device 230 of the pixel structure 300 is electrically connected to the first electrode 340 and electrically insulated from the second electrode 350 . That is to say, in the second embodiment, the first electrode 340 is a pixel electrode. In this embodiment, the pixel electrode 340 can not only span the entire active device 230 , but also only span the drain part of the active device 230 , and the present invention is not limited thereto. When the pixel structure 300 displays a picture, the first electrode 340 receives the data signal from the scan line 210 , and the second electrode 350 receives the common signal from the common voltage source (not shown). In this way, the pixel structure 300 can generate a marginal electric field effect to achieve a display effect with a wide viewing angle.

In practice, the first electrode 340 shown in FIG. 3A also has a stripe pattern 342 and a connection pattern 344, a plurality of slits 346 are defined between the connection pattern 344 and the stripe pattern 342, and the number of the slits 346 is equal to the connection pattern Twice the number of 344. Where these slits 346 are located is where the fringe electric field effect occurs. In addition, in the rectangular pixel area P surrounded by the scan line 210 and the data line 220, although each connection pattern 344 will define two slits 346, there may be two or two slits 346 in the extending direction of the long side. The above slits 346 can allow multiple connection patterns 344 to connect the same two adjacent stripe patterns 342 . Certainly, the pattern design of the slit 346 in the first electrode 340 can also be as shown in the pattern design shown in FIG. 2C to FIG. 2F , but the present invention is not limited thereto.

In addition, the pattern of the first electrode 340 may also have other different designs, and the stripe pattern 342 may not be long strips parallel to each other. 4A to 4D are various first electrode patterns of the pixel structure according to the third embodiment of the present invention. In the pixel structure design of this embodiment, except for the pattern design of the first electrode, the design and arrangement relationship of other elements can be the same as the pixel structure design of the first embodiment or the second embodiment, so only the first electrode will be discussed below. The pattern design will be explained.

Please refer to FIG. 4A first. In the rectangular pixel area P, the first electrode pattern 440 has a plurality of zigzag stripe patterns 442 and connection patterns 444 arranged in a straight line, and multiple stripe patterns 442 and connection patterns 444 are defined. slits 446, the number of slits 446 is twice the number of connecting patterns 444. Each stripe pattern 442 has a bent portion 442A, wherein the bent portion 442A is located between two ends of each stripe pattern 442 . That is to say, the stripe pattern 442 is a "ㄑ" pattern design, but the present invention is not limited thereto. Meanwhile, in this embodiment, the connection pattern 444 is located between two adjacent bent portions 442A as an example, but the invention is not limited thereto.

Specifically, the angle θ between the extending direction of the slit 446 and the long side of the rectangular pixel region P may be 0°≤θ<45°, while in other embodiments, the angle θ is equal to 10°±5°, That is, 5°≤θ≤15°. The slit 446 may have a length l, and a first included angle θ between the long side and the slit 446 and a second included angle ψ between the wide side and the slit 446 , and θ<ψ. In addition, the connection pattern 444 may only be connected between some of the stripe patterns 442 , as shown in FIGS. 4B to 4D . Therefore, although the number of slits 446 is twice the number of connection patterns 444 , there are slits 448 not defined by the connection patterns 444 , so the number of overall slits is greater than the number of connection patterns 444 . Of course, in this embodiment, the angle θ between the slit 446 and the long side of the rectangular pixel region P is fixed, that is, the two slits 446 adjacent to the connection pattern 444 are axisymmetric to the extending direction of the broad side.

The first electrode 440 has a plurality of zigzag stripe patterns 442 , and applying such a design in a liquid crystal display can make liquid crystal molecules present a multi-domain arrangement when displaying. That is to say, the design of the first electrode 420 in this embodiment can compensate the display effect of the liquid crystal display so that the liquid crystal display has better display quality. Of course, the configuration of the connecting pattern 444 in this embodiment also helps shorten the length of the slit 446 .

Furthermore, FIG. 5 shows the first electrode of the pixel structure of the fourth embodiment of the present invention. In the pixel structure of the fourth embodiment of the present invention, except for the pattern design of the first electrode, the arrangement of other components and the connection relationship between the components can be the same as those of the first embodiment or the second embodiment. Therefore, FIG. 5 only illustrates the design of the first electrode.

Referring to FIG. 5 , the rectangular pixel area P of this embodiment has a major axis direction Y and a minor axis direction X. Referring to FIG. The first electrode 540 is located in the rectangular pixel region P and has a first slit Γ ₁ and a second slit Γ ₂ . Here, the first slit Γ ₁ and the second slit Γ ₂ are designed independently and not connected to each other. The first slit Γ ₁ forms a first angle θ1 clockwise with the major axis direction Y, and 0°≤θ1<45°, and the second slit Γ ₂ forms a second angle θ2 counterclockwise with the major axis direction Y, And 0°≤θ2<45°. Here, it is taken as an example that the first angle θ1 and the second angle θ2 are not equal. In other embodiments, the first angle θ1 and the second angle θ2 are axisymmetric to the minor axis direction X, that is, the first angle θ1 and the second angle θ2 may be substantially equal.

In this embodiment, the rectangular pixel region P has a long side parallel to the long axis direction Y, and the relationship between the length of the first slit Γ ₁ or the length of the second slit Γ ₂ and the length L of the long side is: _0.50L <Γ1 or Γ2≤0.52L. In this embodiment, the material of the first electrode 540 is a transparent conductive material, that is to say, the first electrode 540 is a transparent electrode. In the pixel structure to which the first electrode 540 is applied, the second electrode may also be made of a transparent conductive material. However, the present invention does not limit the materials of the first electrode 540 and the second electrode, and they can also be made of non-transparent conductive materials, such as metal, when they are applied to a liquid crystal display in reflective display mode.

In the various first electrodes 240 , 340 , 440 , 540 described above, two or more slits 246 , 346 , 446 may be arranged in the extending direction of the long side of the rectangular pixel region P. As shown in FIG. That is to say, the length of the slits 246, 346, 446 is shorter than that of the known pixel structure design. When the length of the slits 246, 346, 446 is shortened, when the pixel structure is applied to a liquid crystal display, the liquid crystal molecules can recover to their original state in a shorter time after being disturbed. Therefore, the liquid crystal display and the touch display panel with such a design of the first electrodes 240 , 340 , 440 , 540 can have good quality. When the user performs a touch operation and presses the touch-sensitive display panel, the liquid crystal molecules can quickly return to their original state without affecting the display quality.

The various designs of the first electrodes 240, 340, 440, and 540 described above only need to slightly modify the mask patterns for the first electrodes 240, 340, 440, and 540 during the manufacturing process, without causing complicated process steps. change. In short, the manufacturing process of the pixel structure of the present invention is compatible with the existing manufacturing process of the pixel structure.

In more detail, the description of applying the pixel structure of the present invention to a touch-sensitive display panel will be provided below. FIG. 6 is a touch display panel according to an embodiment of the present invention. Referring to FIG. 6 , the touch display panel 600 includes a substrate 610 , a pair of opposite substrates 620 , a light valve layer 630 , a plurality of pixel structures 640 , a touch element layer 650 and a pair of opposite electrodes 660 . In this embodiment, the pixel structure 640 is disposed on the substrate 610 , and the design of the pixel structure 640 may be selected from at least any one of the pixel structures in the aforementioned first, second, third and fourth embodiments. The light valve layer 620 is located between the substrate 610 and the opposite substrate 620 . The touch element layer 650 is disposed on the opposite substrate 620 , and the opposite electrode 660 is disposed between the light valve layer 630 and the touch element layer 650 . For example, the opposite substrate 620 is located between the touch element layer 650 and the opposite electrode 660 .

In this embodiment, the light valve layer 620 is a liquid crystal layer, so the touch display panel 600 may also be a display panel of a liquid crystal display. Of course, the light valve layer 630 may also be other material layers that can provide the function of a light valve under the action of electric field changes. In addition, the design of the pixel structure 640 in this embodiment may be the design of the pixel structure in the above-mentioned various embodiments. That is to say, there may be a rectangular pixel region P on the substrate 610 . Each pixel structure 640 has a first electrode 642 and a second electrode 644 , wherein the first electrode 642 has a plurality of slits 642A located in the rectangular pixel region P. As shown in FIG. The slits 642A have a length Γ. When the length of the long side of the rectangular pixel area P is L, and the length of the wide side of the rectangular pixel area P is W, there is a first angle θ between the long side and the slit, 0°≤θ<45°, and the wide side There is a second included angle ψ with the slit, and θ<ψ, as shown in FIG. 4A and FIG. 4B . Such a pixel structure can provide a good wide viewing angle display effect and improve the quality of the touch display panel 600 .

In practice, the length of at least some of the slits 642A in the pixel structure 640 is shorter than the slit design in the background art, ie, 0.50L<Γ<0.71L, preferably 0.50L<Γ≤0.52L. Therefore, when the user presses the touch-sensitive display panel 600 to perform a touch operation, the liquid crystal molecules in the liquid crystal layer 620 can quickly return to their original state. In other words, the display quality of the touch-sensitive display panel 600 will not be negatively affected by the pressing action of the touch control, so the overall quality will be further improved.

In this embodiment, the touch element layer 650 has a plurality of touch elements (not shown), wherein each touch element (not shown) can be an optical touch element, a capacitive touch element, A resistive touch element or an infrared touch element. In other words, the touch element layer 650 may be composed of elements designed according to various touch sensing principles. In addition, a color filter layer (not shown) may be disposed between the opposite electrode 660 and the opposite substrate 620 to achieve a multicolored display effect. In order to allow light to pass through the opposite electrode 660 for display after passing through the light valve layer 630, the opposite electrode 660 can be a transparent electrode, which is essentially made of indium tin oxide, indium zinc oxide, zinc aluminum oxide or zinc oxide. Made of ingot oxide.

FIG. 7 is a touch display panel according to another embodiment of the present invention. Please refer to FIG. 7 , where the touch element layer 750 of the touch display panel 700 is located between the opposite substrate 620 and the opposite electrode 660 . Under such a configuration relationship, the touch element layer 750 may have a plurality of color filter patterns (not shown). That is to say, the touch element layer 750 can be integrated with the color filter layer to simplify the element design of the touch display panel 700 . Of course, the touch display panel 700 also has the characteristics of a wide viewing angle display effect, good recovery of liquid crystal molecules, and good display quality.

In summary, in the pixel structure, touch display panel and liquid crystal display of the present invention, the extending direction of the slit is close to or parallel to the long side direction of the rectangular pixel area, and the length of the slit is shorter than the known design . Therefore, the liquid crystal molecules in the touch display panel and the liquid crystal display can quickly return to their original state after being disturbed by an external force. In this way, the display effect of the liquid crystal display and the touch display panel will not be adversely affected by the user's touch operation or the user's pressing action. That is to say, the touch display panel and the liquid crystal display of the present invention have good display quality. In addition, the pixel structure of the present invention is generally compatible with the process of the known pixel structure without complicating the process of the touch display panel and the liquid crystal display.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention.
